Abstract (en)

A semiconductor package structure (300) comprises: a high-voltage depletion type semiconductor transistor (304) comprising a source electrode (306), a gate electrode (307) and a drain electrode (305); a low-voltage enhancement type semiconductor transistor (320) comprising a source electrode (308), a gate electrode (310) and a drain electrode (309); a shell (301) comprising a cavity (301-1), a high-voltage terminal (303), a first low-voltage terminal (330) and a second low-voltage terminal (331); and cascade circuits comprising a supporting sheet (302) having a conductive surface (302-1). The source electrode (306) of the high-voltage depletion type transistor (304) and the drain electrode (309) of the low-voltage enhancement type semiconductor transistor (320) are fixed to the conductive surface (302-1) of the supporting sheet (302) and electrically connected to each other. A side of the supporting sheet (302) away from the conductive surface (302-1) is fixed to the cavity (301-1) of the shell (301).
